UNITED STATES NELSON LUNDWALL, OF BROOKLYN, NEW YORK.

PATENT OFFIcE.

HOYRSESHOE.

SPECIFICATION forming part of Letters Patent No. 174,751, dated May 10,1892.

Application filed February 11, 1890- Renewed October 3, 1891. Serial No.407,602. (No model.) i

To all whom it may concern.-

Be it known that I, NELSON LUNDWALL, a subject of the King of Sweden andNorway, and a resident of Brooklyn, county of Kings, and State of NewYork, have invented a certain new and useful Improvement in Horseshoes,of which'the following is a specification.

My invention relates to devices employed for preventing interferenceaction in a horses movements and in particular to an improved horseshoe,and has for its object the provision of a device simple in construction,cheap in manufacture, and efficient in practical use.

To attain the desired end my invention consists in the construction andarrangement of parts hereinafter set forth.

In the drawings which form a partof this specification, Figure 1represents a plan view of the under side of the shoe, and Fig. 2 is aside elevation of my improved shoe.

Like letters of reference, wherever they oc cur, indicate correspondingparts in both the figures.

Referring again to the drawings, A represents my shoe, the outer side ofwhich A is preferably wider than the other, as indicated by the dottedlines, and being ordinarily of an equal thickness throughout.

My shoe is provided with nail-holes of usual construction and ordinarilyhas an integral outwardly-flaring heel A My shoe is also provided withtwo preferably longitudinal heel-calks a (4 with a toe-calk a and with acentral outer quarter-calk a the planes of the upper face of the shoeand the lower surfaces of the calks being parallel. The toe and centralouter quartencalksa (Fare comparatively large and the heel-calks a a arequite small. Thus the greatest weight and largest bearingsurface areplaced where there is most wear without making the shoe unduly heavy.

From experience gained in the treatment of interfering horses I havefound that an interfering horse shod with an ordinary shoe soon wearsthe outer toe thinner, and the bottom of the hoof not being level theinner part of the shoe will strike against the opposite leg. I havetherefore regulated the size and located the positions of these fourcalks so that the wear on, the same will be uniform, and there being nowear on the shoe elsewhere than at the four points a a a a it isinanifest that the two surfaces of theshoe will always be parallel andthe horses foot will be kept perfectly level until the calks areentirely worn away.

From the above description it will be seen that my improved shoes areadapted for universal use and are not confined to cases of interferinghorses, as they correct any tendency to faulty action and keep, asstated, the horses fee: level at all times.

As it is evident that many slight changes in the construction andrelative arrangement of parts might be resorted to without departingfrom the spirit and scope of my invention, I would have it understoodthat I do not restrict myself to the particular construction andarrangement of parts shown and described, but that I reserve the rightto make such changes, and that What I claim as new, and desire to secureby Letters Patent, is

1. A horseshoe of even thickness throughout, provided with an integraloutwardly-flaring heel and with two longitudinal heel-calks and with atoe-calk and also with a central outer quarter-calk, the planes of theupper face of the shoe and the lower surface of the calks beingparallel, substantially as described.

2. A horseshoe of even thickness throughout, provided with two integralheel-calks and with an integral toe-calk and also with an integralcentral outer quarter-calk, the inner half of the shoe being thin anddevoid of calks and the planes of the upper face of the shoe and thelower surface of the calks being parallel, substantially as described.

A horseshoe of even thickness throughout, provided with an integraloutwardly-flaring heel and with a toe-calk and also with a central outerquarter-calk, the planes of the upper face of the shoe and the lowersurface of the calks being parallel, substantially as described.

In testimony of the foregoing specification I do hereby sign the same,inthecity of New York, county and State of New York, this 28th day ofJanuary, A. D. 1890.

NELSON LUNDlVALL.
